Im considering installing a leveling kit on my 2wd 2012 F150. I have no interest in lifting it, I just want to level out the front and put some good AT tires, as I do use the truck off road and for hunting. What do you recommend? Leveling spacers, or leveling shocks such as Bilsteins? I dont mind paying $$$ for the proper setup, as I read some leveling kits put extra stress on the ball joints.
